Could not find module glimmer-reference and Could not find module `ember-resolver` imported from `www/resolver`

Versions that I am using

ember-cli: 2.6.2
node: v8.11.3

After I installed this addon, I received an error on my console.

Please do let me know if I am missing something. Any response is much appreciated. Thank you

Docs says : Supports Ember 2.12, 2.16, 2.18, 3.1, 3.2, 3.3, 3.4, 3.8, 3.9

Update: Even if upgrade to 2.12 and 2.16, it does return the same error as well

Would you mind sharing a demo repo that I can use to dig into this?
